Chart::Graph::gnuplot() |
gnuplot() is a function in module Chart::Graph that lets you generate graphs on the fly in perl. It was written as a front-end application to gnuplot for hassle-free generation of graphs. gnuplot() can be supplied with many of the same options and arguments that can be given to gnuplot. For more information on gnuplot please see http://www.cs.dartmouth.edu/gnuplot_info.html.
#make sure to include Chart::Graph use Chart::Graph; gnuplot(\%global_options, @data_sets); gnuplot(\%global_options, [\%data_set_options, \@matrix], [\%data_set_options, \@x_column, \@y_column], [\%data_set_options, < filename >], ... );
